SPOKE-TENONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 256,897, dated April25, 1882.

Application filed December 5, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHRISTIAN B. HOLMES, of the town of Urbana,in thecounty of Champaign, in the State of Ohio, have invented a new anduseful Machine for Tenoning Spokes; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand Operation of the same, reference being had to the annexed drawing,making a part of this specification.

Myinvention relates to spoke-machines; and it consists in details ofconstruction that will be hereinafter more fully set forth in thespecification and claim and pointed out in the accompanying drawing,which is a perspective view of my device.

Referring moreparticularly to the drawing, A represents a horizontalplate or bed having at one end the spoke-rests (t o and an intermediatespoke-clam-p, b. The rests a a are preferably cast or made in one-piecewith the bar A. The spoke B is passed through the.

clamp b and held firmly by tightening up the tail-tap c, which isscrewed on the shank or projection b of the clamp. At the opposite endof the bed, and at suitable distances apart, are two clamps, D D, whoseshanks pass through the bed and are held in position by suitableset-screws, 0 e5. These clamps hold socurel y an au ger-sh aft, F,having a shoulder, G, upon which rests one end of the feed-lever H, theopposite end of said lever being slotted and attached to the hand-leverK by a pin, L. This hand-lever K is attached to the upper clamp, D. Ahollow anger, R, is attached to one end of shaft F, and a crank-arm, 0,held by a set-screw, P, is attached to the other end of the shaft. Onsaid shaft, between the crankarm and clamp D, is asliding gage, N, heldin any desired position by a set-screw, Q. By means of this gage themovement of the shaft F and anger in the boring direction is limited,and therefore thelength of the tenon may be accurately determined. Whenthe boring is completed the shaft F and anger are thrown back by thelever K, the clamp b unclamped, the spoke removed, and the machine isagain in readiness for another spoke.

Thus it will be seen the operation is simple and quickly done, and asthe several parts of my device are light and preferably made of havehereunto set my handt-his 15th day of November, 1881.
